Can Hi Fin Peppered Cory and Xenotilapia ochrogenys Live Together?

Hi Fin Peppered Cory is a peaceful species (2/10), while Xenotilapia ochrogenys is generally mild-mannered (4/10). This modest difference means Xenotilapia ochrogenys may occasionally assert dominance over Hi Fin Peppered Cory.

Hi Fin Peppered Cory and Xenotilapia ochrogenys both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Worth noting: Hi Fin Peppered Cory is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Xenotilapia ochrogenys is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Hi Fin Peppered Cory (16–23°C) and Xenotilapia ochrogenys (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Hi Fin Peppered Cory (6–7.5) and Xenotilapia ochrogenys (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house Hi Fin Peppered Cory and Xenotilapia ochrogenys together, plan for an aquarium of at least 265 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Hi Fin Peppered Cory and Xenotilapia ochrogenys are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
